Tricking the Computers, deleting the ABS

The ABS on the my '93 sucks... my 70 chevelle stops way better with manual brakes, and the truck stops even better, when i pull the ABS fuses.

but, when i do that the computer freaks out, check engine light comes on, and the speedometer does not work...

so, how can i make the computer focus on running the tuck, so i can focus on driving it? eventually i want to re-plum the brakes all around the truck and completely delete the ASB all together.
this will also make engine swaps easier.
